Magno Thyroid
TSH on TRT
What the number means, why it moves on a protocol, and what people usually do about it.
What it is
Thyroid stimulating hormone is the brain asking the thyroid for more. High TSH means the thyroid is falling behind; low TSH means it is being pushed, or hormone is coming from a pill.
The range
TRT-aware target
0.5 to 2.5 mIU/L
How to read the lab range
Labs quote about 0.4 to 4.5 mIU/L. People feel best under 2.5. Suppressed TSH on T3 or a fat burner is expected.
Why it moves on a protocol
- Hard dieting and low calories push T3 down and TSH up.
- Clenbuterol and T3 suppress it.
- Iodine or selenium running short.
- Plain hypothyroidism, unrelated to the protocol.
What people usually do · not a recommendation
- Retest after two or three weeks eating at maintenance.
- Selenium (200 mcg) and iodine from food are the usual soft supports.
- On T3 or a fat burner, that is the cause; people talk to a doctor before touching it.
How Magno reads it
Import the PDF or a photo of the report and Magno finds TSH on it, keeps every test on one line, shows the change since the last one, and reads it against TRT-aware thresholds rather than the lab's generic range. The panel it belongs to, Thyroid, gets a written verdict with the probable causes and what people usually do.

Questions people ask
TSH high on a cut, is my thyroid broken?
Usually not. A big deficit lowers active thyroid hormone and TSH rises to compensate. It settles when calories come back.
